Abstract :In this study, robust and high-performance vector control of a rotor side converter insert ignore into journalissuearticles values(RSC); was performed for stability and efficient operation doubly fed induction generator insert ignore into journalissuearticles values(DFIG); based on the variable speed wind turbine insert ignore into journalissuearticles values(VSWT);. The mathematical model of the DFIG is simulated in the computer. Amplitude and frequency of the voltage in the DFIG were controlled for different values of load and variable speeds. In the experimental study, a DFIG-based wind turbine system was set up in the laboratory. The field position of the stator was detected from stator voltages by a phase-locked loop insert ignore into journalissuearticles values(PLL); circuit. The rotor position was measured with an incremental encoder connected to the rotor shaft of the DFIG. The angular position of the slip was calculated by the difference between the rotor and the stator field positions. The frequency and amplitude of rotor currents were determined with the angular position of slip. To generate output voltages of converter feeding rotor windings, the space vector pulse width modulation insert ignore into journalissuearticles values(SVPWM); technique was used. In the experimental study, the RSC was controlled with the DS1103 board. The prepared experiment set was tested at different operating speeds.
